Just putting the feelers out there to see if anyone else is having issues with this release?
We have 3 main issues.
Captive portal redirects are randomly failing for IOS users, they can not get to the CP landing page, even if I enter the URL directly. Other users attached to the same Ap have no issues. Give it a little while and then they are fine, and someone else has the issue who was previously fine.
IOS/Apple users just suddenly appear to lose connectivity. Actually they are associated, but their speeds are so slow, it is impossible to load any web pages. This behaviour will carry on accross AP's when they roam, and then just as suddenly, normal service is resumed and they are fine again. Other users in the ame are unnaffected.
We are getting lots of complaints from Apple users over general wireless performance, as ever with no detail, however Im finding if I disable band steering for the users, their performance improves dramatically.
The only thing that is common is that for IOS users who complain, they are all on 12.1.4.
I do have a TAC case open, who have been excellent, but due to the highly random nature of who is affected, it is proving a nightmare to troubleshoot.
As a fix we are going to move to 8.4.0 to see if that is any better (40 pages of bug fixes in the release notes!) and I have a couple of questions?
Is 8.4.0 the very latest release?
I remember there was a build of 8.2 that was considered very stable - can anyone advise on which version (that is my plan B)
